The theory-oriented approach to the final thesis in higher education is still dominant at the Master as well as Bachelor level. We believe, however, that at the Bachelor level a practice-oriented approach would be more appropriate. Our research as presented below explores the possibilities of a practice-oriented approach to the Bachelor's thesis in teacher education. Semi-structured interviews form the basis for a grounded theory regarding the various current final thesis models and the conditions in which these have to be realized. The conclusion is that the portfolio as final thesis proves to be a satisfactory practice-oriented alternative to the highly criticized traditional final thesis.
